Straight to the point: Chunky Snake is a starting step of 150 ms that tightens as you eat, playable in your browser right now. It is tuned for quick runs, honest difficulty, and controls that make sense the first time you touch them.
The snake moves in fixed steps; each pellet eaten adds length and slightly tightens the interval, so the game gets harder the better you do. Walls and your own tail both end the run instantly. The a starting step of 150 ms that tightens as you eat, and the ramp is tuned so mid-game still feels fair.
It suits anyone with a queue to wait in or a kettle to watch: students between classes, commuters, parents stealing ten quiet minutes. There is no meta-progression to lose and nothing to catch up on - a week away costs you nothing but a little sharpness.
Grow the longest snake without touching walls or tail.
Read Chunky Snake as a Arkad Shelf game first and a Arkad Shelf game second. The shape explains how the session will end; the group explains what it will ask of you before that.
Mechanically it stays close to its tag set — arcade, survival, classic — and does not add a second system on top, which is why it survives repeated play better than it looks like it will.
If you are choosing between this and something similar, start here when you have Easy energy and elsewhere when you do not. Chunky Snake does not pretend to be more than it is.
